The pronunciation of Spanish is not hard at all. All you have to do is say the word as it would normally sound. Once you know what some groups of letters sound like, such as "ch" or "ll&...

Firstly we must change it into a form we can deal with. To do this we take the natural log (ln) of both sides.ln(y)=ln(a^x) ln(y)=x(ln(a))    using our rules of logsFrom here we differentiate. T...

For this we are going to test our knowledge of discriminats and factorisation. Firstly we will format the equation as (m+8)x²+8x+(m-7)=0From here we can see it takes the form ax²+bx+...

Every word has a function in a sentence. Sometimes, we can take words away and the sentence still makes sense. However, at other times, some words are essential for the sentence to not sound 'odd.' Say...

We know that for equation ax^2+bx+c=0
a = 2,b = 3,c = -5
If the roots x1 and x2 are real numbers:
x1 + x2 = -b/a = -3/2
x1*x2 = c/a = -5/2
